Image noisy. took another look at the Ultra60 and the images seem better. Maybe it just took some time for the tip to stabilize. The images are still pretty soft and they seem noisy so we would still like you to come and take a look at our system. I took a few measurements. Specimen current (Faraday Cup, 5mm WD, 30 痠 aperture): 5KV = -158pA 10KV = -201pA Emission current: EHT off = 318 渙 EHT on = 256 渙
